DERMATOPATHIES IN BRAZILIAN PRODUCTION ANIMALS

In Brazil, the production of animals stands out considerably among the most varied zootechnical species; however, maintaining the health of herds is still one of the main bottlenecks that the country needs to overcome in order to remain in this prominent position in the competitive market environment. The integumentary tissue is a constant target of pathogens or environmental disorders and is often the first to show signs of illness on the property, so that greater attention should be given to this organ as a tool to prevent the advancement and perpetuation of diseases and, consequently, reduce the impacts of diseases on the farm. The aim of this thesis was to provide an update on the main dermatopathies in zootechnically exploited animals in Brazil, with an emphasis on various production systems. Therefore, the study was divided into two parts: the first contains a review of the general literature, which specifically addresses some of the most common skin diseases in the aquatic and terrestrial production environment, as well as the repercussions of these diseases. The second part is divided into three chapters and contains: a) a literature review called “skin diseases of donkeys and mulesan update”, currently published in the international journal Animals (impact factor 2.752); b) a literature review entitled “Skin and cuticle changes in diseases of farmed fish and shrimps in Brazil”, which is under consideration in the International Journal Aquaculture (impact factor 4.242) and c) a scientific article “Dermatitis caused by Tephrosia is noctiflora a systemic granulomatous disease?”, which will be submitted to the national journal Pesquisa Veterinária Brasileira (impact factor 0.584). These works indicate that the skin is frequently affected, especially by traumatic and toxic disorders, which are constantly studied and reported in terrestrial species. Cultivated species, on the other hand, still lack studies that allow for the recognition of mechanisms and patterns of cutaneous and cuticular diseases, particularly those of non-infectious origin. In all production spectrums, however, the negative repercussion of dermatopathies for the producer is evident. It is hoped, with these studies, that skin disorders receive due attention from producers and professionals who deal in the field with species of zootechnical interest in Brazil.
